Key Features
- Low power consumption: Operates from a single 2.7 V to 5.5 V supply with a typical power consumption of 11.8 mW.
- On-chip reference: The device features an on-chip reference with 5 ppm/°C temperature drift, which can be enabled via a software write. External reference option is also available.
- I2C-compatible serial interface: Supports standard (100 kHz), fast (400 kHz), and high-speed (3.4 MHz) modes.
- Guaranteed monotonic by design: Ensures that the output voltage always increases or remains constant with an increase in the digital input code.
- Rail-to-rail output amplifier: Allows for full-scale output voltage range.
- Power-on reset circuit: Ensures the DAC output powers up to 0 V or midscale and remains there until a valid write occurs.
